Application filed November 11, 1904. Serial No. 232,299.

To all, whom it may concern.-

Be it known that I, H ERMANN Duns, a citizen ofT-lrermany, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in TrolleyWVircdtepair llevices; and l do hereby declare the followingto be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to a novel construction in a device adapted for use in repairing trolleynvires and which is particularly adapt ed to remain fixed to a broken wire as a temporary repair until the Wrecking-crew can reach the point at which the break occurs and repair the same, the object being to provide a simple and efficient device of this character; and it consists in the features of construction and combinations of parts hereinafter fully described and claimed.

in the accompanying drawings. illustrating my invention, Figure is a side elevation of a repair device constructed in accordance with my invention. Fig. 2 isa vertical transverse section of same on the line 2 2 of Fig. 1. Fig. 3 is a vertical transverse section on the line 3 3 of Fig. 1. Fig. 4 is a detail horizontal section on the line 4 4 of Fig.1 on an enlarged scale.

My said device comprises a member A, which is composed of two plates or bars B and 0, each of which is provided in its inner face with a longitudinal groove or recess D, in which a rack-bar E is adapted to be received and is longitudinally movable. Between said members or bars B and C a plate F is interposed, which serves to isolate said recesses from each other and to form a bearing-plate for the inner faces of said rackbars F. Mounted in each ofsaid recesses adjacent one end of the bar is a pinion Ur, which is rigidly mounted on a transversely-disposed shaft H, passing through both of said plates B and U and which at one of its outer ends carries a ratchet-wheel J,-adapted to be engaged by a pawl K, pivotally mounted on each of said plates or bars adjacent one end' thereof. The

extreme outer end of said shaft H is squared,

as at L, to receive a wrench M, by means of which said shaft is turned to impart longitudinal movement to said rack-bars E. The said plates or bars B and U are bolted or otherwise secured together and on their lower edges are slightlycurved so as to terminate in a ii-shaped convex edge, over which the trolley-wheel is adapted to travel. The extreme outer ends of said rar-lcbars it) are enlarg'ed to provide an upwardly-exteruling pro jection N. on which is mounted a suitable clamping device or vise O to engage one end of the wire P. ()n the upper edge of each of said bars E and O and at opposite ends of the membcrA, I also provide a vise Q, which is likewise adapted to receive and engage one end of the broken wire. The said rises U and Q each comprise a vertically"disposed standard or guide member, in the overhang ing upper end portion of which a set "crew R is mounted, which bears upon a vertically movable block or shoe S, mounted in guides in said standard and which coacts with a block T to receive and engage the wire, each of said membersSand T being provided with a semi-- circular groove to receive said i re. The said projections N of said 1%t(3li321l -.i are relatively otiset so as to bring the visas clamir; ing members 0 and (.1. in perfect alineui at with each other.

The operation of my device is as follows: The said device is designed to carried on, the trolley-cars to enable the crews to make temporary repairs without waiting or relying on the Wrecking crew, and thus wasting a great deal of very valuable time. When the break occurs, members oi the crew ascend to the roof of the car and by zncansoi' any suit-- able device first secure hold ofone end of the broken trolley-wire and clamp the same in one of said Vises or clamping devices (It, the rack carrying same having been previously moved to the outer limit of its movement. The other rack-bar F is then likewise moved to the outer limit of its movement and both. the pawls K thrown into engagement with the ratchet-wheels J toprevent such rack-bars from being entirely pulled out of said mean her A. When thus extended, my said device covers considerable length, and by then on gaging the other end of the broken wire and clamping same in the vise O .of the second rack-bar the said/ rack bars may obvionsiy be drawn to the inner limits of their mrwenieut and the ends of the wire thus brought closer together. It is obviously desirable that the wire should be stretched so that it will not sag, as this renders the passage of the car more diliicult. Hence when both ends of said wire have been brought together as close as possible by the rack-bars E the ends thereof are secured in said vises Q and clamped therein.

si ed toward the outer limit eat and. the wire again clamped i l then released from said raeinba'rs then again moved limits of their movement. is repeated until the trolleyied e desired tension.

aily engaged by both sets j and the said member A is "wire temporarily. The ,t; temporarily repaired with rapidity, and thus long delays nurse at great inconvenience to loss to traction companies my inventiona of the hind specified comprisa member provided with i l ngitudinal passages, a rack-bar shy in each of said pasat its ends clamping dohe ends of the wires to be P jeurnaled in said meminnions engaging said rack- Then 1 thereon and remains a on said cranks, pawls on 7 devices at the ends of said member adapted to receive the ends of the Wires as the same are brought together, said last-named clamping devices being so disposed that the extreme ends of the wires may be joined between the same.

2. A device of' the kind specified comprising in combination a member having two parallel longitudinal passages and curved at the ends of its lower edge, raclebars movable in said passages and having curved upwardlyoffset ends, clamping devices carried on the upper portions of said offset ends, clamping devices on the ends of said member in alinement with said clamping devices on said rackbars, crank-shafts journaled in said member and carrying gear-pinions meshing with said rack-bars, ratchet-wheels on said cranlvshafts and pawls on said member adapted to engage said ratchet-wheels.

In testimony whereof I have signed my name in presence of two subscribing witnesses.
